Quoted by Phone Arena from a forum member PCBeta, besides Windows Blue is also no mention another name, namely "Windows 9 Dev".
The successor of Windows 8 is rumored to be a cheaper version of Windows that will have a new user interface, including the platform and the price changes. With the holding of low-cost version of Windows seems Microsoft wants everyone Parties can use the Windows Blue.
View live tiles like Windows Phone 8 will also display the latest operating system from Microsoft.
To view the desktop also remain as previous versions of Windows, but there are changes to the look of the interface, which looks more "flat" in order to align with the visual concept promoted by Metro-style user interface.
Possible Microsoft will use the new Windows kernel, version 6.3, which will make things run better. Besides Windows Blue also will support for tablet-sized 7 and 8 inches, which is still not in the Windows ecosystem.
Other interesting news from Microsoft is the existence of a free update Windows Blue mid-year 2013, it is probably because Microsoft wants the successor to Windows 8 is used by as many users as possible.
